stacktrace

please provide some more details, tried to generate rest from db on gf3.0.1 with some mysql datasource and have no nullpointer.
is it reproducible always or not, is it reproducible with new nb user dir or with some old/or imported from older nb. what settings are used in wizard - datasource, package, names etc. 

Also I see there are a lot more exceptions in log for different areas.

I can't reproduce this now with latest build and a clean nb user dir

thanks, >P4 for now as it may be quite rare or not reproducible any more but it still will collect same reports if it's something new.

same problem here, tell me what info you need and i'll try to provide it :)
